Cell Phone Battery Concept Charges with a Flick of a Finger

What if you no longer needed counter space for all your portable gizmos to charge on? You could toss out all those mismatched power cords, and instead have your finger play hula hoop champion in order to juice up your handhelds. What would you do with the extra space?

Designers Song Teaho & Hyejin Lee have come up with a concept battery that charges by being swung around. The Swing Your Energy Charger takes an estimated 130 swings around your index finger to power your phone for one last conversation.

Unfortunately Teaho and Lee's battery can only be charged just enough for one last call, but what if the battery could be modified to get all its power from your finger movements? Or better yet, what if the battery could be modified so that any phone movement -- from being in your bag to being moved from one ear to the other -- would charge the battery?
